room. Close and insulate any windows or doors to other rooms.

Solution: Check that the air conditioner is compatible with the square footage of the room. You

may need additional cooling or another air conditioner.

Possible Cause: The unit was turned on late in the day, after the room temperature became high.

Solution: Turn the air conditioner on earlier. Turning the air conditioner on early instead of

waiting until the hottest point of the day will allow the unit to be more effective. The air

conditioner will not have to work as hard to cool the room down and maintain the set

temperature. Add a fan to help circulate the air.

Possible Cause: The exhaust hose is too long, has a sharp bend or exhausted air is leaking.

Solution: Keep the exhaust hose as short and straight as possible. The exhaust hose removes heat

the exhaust hose if hot air is leaking into the room.

straight as possible.

Solution: The window screen does not need to be removed when installing the window slider

kit.

Problem: The heating function is not working (applicable models)

Possible Cause: The room temperature is too low.

Solution: The heating function of the air conditioner does not operate when the temperature is

below 45°F. Ensure the room temperature is above 45°F.

on (applicable models). Note: some models have a rubber stopper and others have a plastic drain

cover and rubber stopper. Refer to the user manual for more information. It is normal for the unit

to collect more condensation and need to be drained more often than it does in Cool mode as the

self evaporative feature does not engage in Heat mode.

loose internal connection. Please contact Whynter Customer Support for service. ”
